KEY MESSAGES

- Seasonally cold and breezy through Friday, with a slow warming trend this weekend into next week.

- Dry conditions are expected through the middle of next week, before a more active pattern is re-established.

SHORT TERM /THROUGH FRIDAY/

Issued at 337 PM CST Thu Nov 12 2026

The current upper air analysis features a fairly amplified pattern over the CONUS, with a deepening upper trough over the Great Lakes region and upper ridging over the intermountain west. This is resulting in a deep northerly flow regime across the upper Midwest with some of the coldest air of the season advecting swd across the region.

As is typically the case in these CAA regimes, sct/bkn stratocumulus clouds continue to advect swd across IA/IL. Expect this to continue tomorrow into tomorrow night per the persistent cyclonic flow, with partly to mostly cloudy skies expected. CAA will drop 850mb temps from -5C to -8C tonight and tomorrow. Although winds will not fully decouple overnight, expect low temps tonight from the mid 20s north, to around 30F south. Seasonally cold conditions will continue tomorrow, and nudged temps down a few degrees, preferring a blend of raw model temps. Highs will only reach the upper 30s north to the lower 40s south. Again, with very thin/limited moisture, expect dry conditions.

LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/

Issued at 337 PM CST Thu Nov 12 2026

Surface high pressure will slide eastward this weekend into early next week. This will keep conditions below normal with lows in the 20s and highs in the 40s through this weekend along with more than ample sunshine. As the high slides to the east of the area next week, return flow will allow for temperatures to gradually rise toward climatological values for mid-November. Mid-levels in this extended period will be largely dominated by a ridge of high pressure until mid to late next week. Outside of a shortwave trough scooting south of the area late this weekend and early next week with any moisture well south of the area, the next chance for rain will be late next week, perhaps later. Toward midweek is when a lead shortwave trough will be lifting northeastward toward the region and could offer the first chance for rain, though this may wait until a trailing trough digs and sprawls over the Southwest by the following weekend.

AVIATION /00Z TAFS THROUGH 00Z FRIDAY/

Issued at 520 PM CST Thu Nov 12 2026

Northerly winds will prevail through the TAF period and dance around 360 degrees with regularity. At least sporadic gusts in the 15-20 kt window will be seen too before dropping off markedly near sunset on Friday. Stratocumulus between 3kft and 4.5kft will be broken more often than not tonight, then vary between scattered and temporarily broken during Friday.
